Or the cost/salary of an EE engineer. Can easily run 100-150$/hr. 2k$ license = 13-20 hrs max saved. In 1 year! That's only 15-25min a week.
For a business having a full-time CAD user, it's a no brainer. For a private individual, maybe not so much.
The amount of busy-work I've seen a colleague perform with Eagle was immense. Every BOM had to be manually formatted and edited.
Editing schematics and PCBs was tedious. Right click -> "select group". Drag. Okay, use tool, move. Oof, misclick. CTRL+Z. Oh lost selection.. okay again.. Right click -> "Select group". Drag. Okay, now I want to edit the footprints of all precision resistors from 0420 to 0603. Oh I need to do it 1 by 1? Okay.. right click, edit properties.. paste. Only 15 more dialogs to go..
I agree with Nctnico that KiCad has completely voided the need for Eagle. However, I never think the canonical entry of designs is a problem with these CAD tools. You can pretty much represent any schematic/PCB artwork in all CAD packages nowadays. However, how easy/quick it is to draw&edit. Altium is still miles ahead. To me, Altium feels like editing using easy to edit sticky notes, while Eagle felt like trying to draw and revise schematics with acrylic paint and perma markers.
E.g. in Altium you have property filtering, property querying, stack based selections (instead of "tools") and selection editor. I use it all the time. I don't think Eagle has any of this, or not in the versions when I made the jump. I think in KiCad you can do certain stuff with the scripting language.. which is useful, but it's not going to be a 30sec job for the odd things to change on a PCB.
